Seatbelt pretensioner shield and heat energy dissipator

A vehicle comprising:

• a vehicle structure;
• a vehicle seat mounted to the vehicle structure;
• and
• a seatbelt system configured to secure an occupant of the vehicle in the vehicle seat, the seatbelt system having:
• a lap belt configured to secure the occupant in the vehicle seat;
• and
• a lap belt pretensioner configured to pull and secure the lap belt around the occupant, the lap belt pretensioner including:
• a pyrotechnic device configured to generate a force directed to tension the lap belt around the occupant and emit an exhaust gas including particulates at high pressure and high temperature as a byproduct of the generated force;
• a housing configured to retain the pyrotechnic device and defining an exhaust passage configured to expel the exhaust gas from the lap belt pretensioner;
• and
• a shield arranged over the exhaust passage and configured to at least one of collect and deflect the emitted particulates and dissipate heat energy thereof.
